‘China-Russia-Canada-America line’ would run for 13,000km across Siberia and pass under Bering Strait through 200km tunnel

China is considering plans to build a high-speed railway line to the US, the country’s official media reported on Thursday.

The proposed line would begin in north-east China and run up through Siberia, pass through a tunnel underneath the Pacific Ocean then cut through Alaska and Canada to reach the continental US, according to a report in the state-run Beijing Times newspaper.

Crossing the Bering Strait in between Russia and Alaska would require about 200km (125 miles) of undersea tunnel, the paper said, citing Wang Mengshu, a railway expert at the Chinese Academy of Engineering.
